Sponsor a category
Testing labs, calibration providers, NDT equipment vendors, and standards/accreditation associations can run a labeled placement on the guides buyers actually read, or in the sourcing brief. Always marked as paid, never a ranking, and never a change to editorial content or ordering.
Audience and traffic figures are shared on request. We do not publish unverified metrics, run fake reviews or ratings, or sell ranking placements.
Sponsorship pricing by category
Priced by real, documented buyer search demand (Ahrefs), not guesswork. Higher-demand categories carry a higher sponsorship rate; everything else is base rate. See the demand figure on each guide page.
| Category | Demand tier | Sponsorship rate |
|---|---|---|
| How to Choose a Materials Testing Laboratory | High demand | $149/mo |
| How to Choose an Environmental Testing Lab | High demand | $149/mo |
| How to Choose a Chemical Testing Lab | High demand | $149/mo |
| How to Find an ASTM-Accredited Testing Lab | High demand | $149/mo |
| What Is a Third-Party Testing Lab (and When You Need One) | Standard | $99/mo |
| How to Choose a Product Testing Laboratory | Standard | $99/mo |
| Failure Analysis Laboratory: A Buyer's Guide | Standard | $99/mo |
| NDT Testing Services: A Buyer's Guide | Standard | $99/mo |
High demand = real Ahrefs search volume of 100+/mo or CPC of $10+ for that category's primary keyword. Categories without a reliably pulled Ahrefs figure default to standard rate rather than an assumed premium.
Founding advertiser opportunity
This directory is newly built and does not yet have paid advertisers. We would rather tell you that plainly than pad this page with logos or reviews that are not real. Get in early: founding Featured and Verified partners lock in current pricing and get first placement as the guide pages accumulate search traffic.
